WASHIINGWMACHINE.

SPECIFICATION forming' part of Letters Patent No. 672,318, dated April16, 1 901.

Application filed July '7, 1399. Serial No. 723,100, (No model.)

To all whom it may concern:

Be it known that I, WILLIAM DREVER, farmer, a subject of Her Majesty theQueen of the United Kingdom of Great Britain and Ireland, anda residentof Kaurihohere, in the county of Whangarei, provincial district ofAukland, and Colony of New Zealand', have invented certain new anduseful Improvements in Washing-Machines, of which the following is aspecification.

l The invention aims to construct a machine of this character which isparticularly adapted for Washing clothes, cotton goods, woolen goods,flax material, whether manufactured or in course of being prepared fromthe raw article, and every class of goods capable of being Washed ortreated by the same.

Briefly described, the invention consists of a pair of reciprocating andstep-bystep or intermittent rotary corrugated rollers mounted in asuitable frame, having their shafts journaled upon smallfriction-rollers angularly arranged while their inner ends are connectedto drive-rods attached to a crankshaft which when operated imparts tothe rollers a reciprocating motion, while the step-by-step orintermittent rotary movement is obtained by ratchet-wheels secured tothe end or ends of the corrugated rollers and which are actuated bymeans of suitably-disposed pawls carried by levers operating uponguide-bars.

The invention further consists in the novel combination and arrangementof parts hereinafter more specifically described,illustrated in theaccompanying drawings, and particularly pointed out in the claimshereunto appended.

In describing the invention in detail reference is had to theaccompanying drawings, forming a part of this specification, whereinsimilar letters of reference indicate corresponding parts throughout theseveral views thereof, and in Which- Figure 1 is a top plan view of themachine. Fig. 2 is an end view thereof, showing the friction-rollers andthe shafts of the corrugated rollers journaled upon the same. Figs. 3and 4 are a plan and a side view, respectively, of one of the guides.Figs. 5 and 6 are side views of modied forms of guides. Fig. 7 is aperspective view of the reciprocating rollers and their operatingmechanism, the frame being removed therefrom.

Referring to the drawings by reference-letters, A indicates a suitablesupportingeframe, within which is arranged the rollers B and B', havingtheir peripheriescorrugated and each provided with ashaft C C',respectively,which are journaled in the transversely-extending supportsD D' upon the frame A. The shafts C and C' are respectively connected tothe yokes E E' of the drive-rods F F', attached to the crank-shaft G, asat H and H'.

J denotes an operating handle for the shaft G.

The rollers B and B' have respectively connected to their inner ends theratchet-wheels K and K', which are engaged and operated by means of thepawls M M', pivoted at one end to the levers L and L', mounted upon theshafts C and C'. The free ends of the levers L and L' project beyond thepivoted ends of the pawls M and M' and operate upon thelongitudinally-extending and inclined guidebars N N and O O',respectively, the former being suitably secured to the transverse support D and having formed integral therewith the outwardly-extendingupwardly-inclined yoke-shaped guide-supports P and P', carrying thedownwardly-extending pivoted guidearms S S'. These guide-arms S and S'are inclined in an opposite direction to the inclination of theguide-bars O and O'.

The shafts C C' operate through suitable stuing or packing boxes (notshown) and which are connected in any desirable manner to the transversesupports D and D'. One end of each of the shafts C and. C' rests uponangularly-arranged friction-rollers T, located in the frames U.Ordinarily this frame U will be inserted into the supportsD or D', asshown in Fig. 2. I do not, however, limit myself to the form of theframe U, nor the particular manner in which it is secured in thetransverse support D. Said frame U has its center cut out, so that theroller T can be fixed within it and jou rnaled to its sides in anysuitable way that will permit the roller T to rotate with the action -ofthe shafts C and C', snii'icient space being left between the roller Tand the frame U to allow the shafts C and C' to pass freely through,while they partly IOO rest upon the inclined roller T, as shown. Asmooth roller W is journaled on the top of the frame A above one of therollers B and B. Brackets X are fastened to the levers L and L', asshown in Figs. l and 7, which contact with the ratchet-wheels K and K toretain the levers in position.

The machine when adapted for use may rest upon or be connected towashtubs or troughs, or it may be secured to a post or bracketed to awall or placed in any desirable position that will permit the operationthereof. To operate the machine, the handle J is turned. This rotatesthe crank-shaft G and imparts an alternating reciprocating movement tothe drive-rods F and F', causing thereby an alternating reciprocatingmovement of the shafts C and C' and the rollers B and B. While theroller B is reciprocated the outer end of the leverL moves along theguide-bar N, then along the guide-arm S, from the top of which it dropsover onto the guide-bar O just as the back stroke. of the roller B isfinished. Then as the roller B is reciprocated forward the lever L movesup the guide-bar O, lifts up the lower end of the guide-arm S, andpasses along the guide-bar N until the forward movement of the roller Bis discontinued, when it again moves with the back movement of theroller on the guide-bars N O and guide-arm S, as heretofore described,continuing such movement upon the guide bars and arms as long as theroller B is reciprocated. The result of this operation of the lever L isthat the pawl M engages and presses against the teeth or notches of theratchet-wheel K, causing thereby the roller B to rotate inwardly,

s which gives it a step-by-step or intermittent rotary movement inaddition to the reciprocating motion which it receives from the driverodF. The roller B' alternates in its operation with that of the roller B,which is exactly the saine, and rotates inwardly in the i same manner asroller B, so that when one is moved forward the operation of the otheris,

just the reverse. While these two movements are given to the rollers Band B' the clothes, fiaX fiber, or other material are passed over theroller W and in and between the corrugated rollers B and B and arethoroughly cleansed by the double movement and action of the corrugatedrollers. The roller W serves as a guide to the material passing betweenthe corrugated rollers, and it may also be used to support the materialwhile some portion of the latter is being specially dealt with.

O O. This will be as indicated by the'reference character O2 P2; or theform of guide- -bar may be employed as shown in Fig. 7,

which is constructed with an adjustable slope or incline, as at O3, toincrease or decrease the ratchet motion, and which may be regulated by asupport or strut P4, hinged to and beneath the upper end of theguide-bar and suitably adjusted to the guide-bar frame P3.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

l. In a washing-machine, the combination of a pair of reciprocatingrollers, operating means therefor, a lever-and-pawl mechanism engagingsaid rollers for intermittently rotating the same, and guide mechanismarranged in suitable relation to said rollers and engaged by said leverfor operating the latter, imparting thereby a rotary movement to thesaid rollers.
